"Data contained in this web site have been collected and processed cooperatively by the University of Idaho, Idaho Cooperative Fish and Wildlife Research Unit and NOAA Fisheries. Data were collected to assist managers and researchers with operational decisions to best manage salmon migration and passage within the Columbia River hydrosystem. Funding was provided by the U.S. Army Corps of Engineers. When citing these data, please refer to the Adult Anadromous Fish Radiotelemetry Project at http://www.cbr.washington.edu/rtag/. In addition, please notify Christopher C. Caudill or Brian J. Burke prior to publishing or presenting data or data summaries contained in this site."

"This project has been on-going since 1996. To date, we have radio tagged spring, summer, and fall Chinook salmon and steelhead during multiple years and sockeye salmon during one year. We also have a companion project to evaluate the passage of Pacific lamprey in the lower Columbia River. Studies are primarily funded by the U. S. Army Corps of Engineers with technical assistance from the U. S. Geological Survey, NOAA Fisheries, Bonneville Power Administration, Bureau of Reclamation, and College of Natural Resources at the University of Idaho."

"Due to the large volume of data and the numerous requests for data access, we could not efficiently respond to individual data requests without dedicated funds. We therefore created this new web site to provide data access to a wide range of users. This includes researchers seeking to analyze in further depth or in novel ways the data contained in our database as well as individuals simply curious about the behavior of salmonids. Our expected primary audience, however, is the U.S. Corps of Engineers employees, who plan to use the data for hydropower facility operational decisions."

"Data contained in this site are pre-processed. Due to the nature of radiotelemetry data, much of the data can be eliminated as noise prior to analysis. The remaining data are summarized by placing codes on particular records, each code indicating a particular behavior by a fish. These 'coded' records are the main content of our site. Without in-depth knowledge of the nature of radiotelemetry data, the meaning of the codes used, and the locations of all our radio receivers, data contained in this site may be very difficult to interpret. We have tried to make this as straight forward as possible."
